There is a known problem with post-linkage that we have not yet resolved. The corruption problem happens when a Moderator deletes/moves a post. The move goes okay, but the Forum that the post was moved from will still show it as the 'latest post' - even though it is no longer there. When you click on the post (in the latest post area) it sends you off to the Forum that the post was moved to.

Use the Site Usage Forum to report problems - DO NOT send Mod Alerts for system errors - the Moderators cannot correct this type of error. Until the problem is resolved, using the 'latest post' link on the Forum Listing page may not take you to the correct Forum.
